Changing out new Tahoe icons?

Is it possible, or not, to revert to the pre-Tahoe icons? I know there are user options to tint or whatever, but the Clock icon is very faint now, appearing as mostly just a white area in some circumstances. The pre-Tahoe version is easy to identify at a quick glance as being the clock. My personal reaction is that the old Clock icon is more in the new style (compare the new Finder icon) than is the new Clock icon. I would also change back the new map icon, which is just a thick vertical line with the capital A in the middle of it, which means not much at a quick glance to someone who does not spend a lot of time on Apple maps.
